CORNER STRUCTURE FOR CARS.

Specication of Letters Patent.

Patented Nov. 3, 1908.

Application tiled May 1, 1908. Serial No. 430,321.

To all whom it may concern.'

Be it known that I, SAMUEL M. CUnwEN, a citizen of the United States,residing in Haverford, Pennsylvania, have invented certain Improvementsin Corner Structures for Cars, of which the following is aspecification.

My invention relates particularly to that class of passenger cars inwhich the corner posts are made so as to provide for the reception of asliding door to extend over the platform.

In passenger cars, especially of the surburban or trolley type, theplatform is a step below the loor of the interior of the car and if asliding door is used it must either eX- tend on a level with the floorof the interior of the car or the transverse end beams of the car mustbe cut away for the reception of the door, so as to bring the lowerportion of the door on a line with the platform. It has been impossibleto construct a car according to the method last described.

The object of my invention is to provide a foot structure for the propersupport of the end posts of the car, so that the channel for thereception of the sliding door can eX- tend to a point on a line with theplatform of the car without weakening the car at the corner. This objectI attain in the following manner, reference being had to theaccompanying drawing, in Which:-

Figure 1, is an elevation of one lower corner of a car showing theplatform and illustrating my invention; Fig. 2, is a sectional View onthe line 2 2, Fig. 1; Fig. 3, is a perspective view of the corner'structure; and Figs. 4, 5 and 6, are detail views of the cornerstructure.

A is the body of the car having a floor a.

B is the platform havin a fioor b.

C is the end beam of t e car which must be securely fastened to theframe of the car and to the vertical corner posts D, D. These cornerposts are spaced a sufficient distance apart to form a channel d for thereception of a sliding door which is to inclose the platform or aportion of the platform; the lower portion of the door being on a linewith the platform.

In order to properly support the posts D, D and to stifen the corner sothat it willl be as strong as a solid corner, I providea foot structureE made as clearly shown in the drawing, having two vertical members cand e. In the member e is a socket e for the reception of the lower endof the post D and in the member e is a socket c3 for the lower end ofthe post D. The members e, e are spaced apart, forming a channel d beinga continuation of the channel d for the reception of the sliding door.The base E of the foot structure is on a level with the floor Z of theplatform B so that a door arranged to slide in this channel can beprojected to entirely close the platform. This is of particularadvantage when the only door of the car is the door that incloses theplatform; the door in the end partitions separating the platform fromthe body of the car being dispensed with.

The lower end of the socket e3 receives the end of the transverse beamC, as clearly illustrated in Fig. 1, as the corner post D extends to thebase of the structure; while the post D rests upon the beam C. Thestructure E has reinforcing flanges i, i which act also as guides forthe door and has stiifening brackets i on its under side to reinforcethe base plate and has a rear stifening member i2 to give strength tothe entire structure. Thus it will be seen that I can make a car'structure in which I am enabled to provide a channel for a sliding doorat the corner of the car without weakening the car structure.

While I have shown a articular form of corner structure E, it will eunderstood thatthis structure may be modified considerably, dependingupon the ty e of car to which the improvement is ap lie In the presentinstance the corner osts D, D are of wood and the sockets are arge toreceive the corner posts, but if corner osts of iron are used, then thesockets will e of such a size as to receive them. The reinforcing angesmay be made of different shapes.

I claim 1. The combination in a car, of two corner posts, and astructure having two vertically projecting members spaced apart to forma continuation of the channel betweenn the posts and adapted to receivethe ends of the osts.

2. The combination in a car in whic the floor of the body of the car isabove the iloor of the platform, of a corner structure situated at thecorner of the car and adapted to receive the end of the transverse bea-mand the corner post, and having a channel formed therein extending bclowthe floor of the oar body.

3. The combination in a car, of a transverse beam at the end ofthe earbody, a plat form at the upper surface of the car bottom, two cornerposts spaced apart to form a channel, and a structure having sockets toreceive the corner posts and the beam, and hav ing a channel forming acontinuation of the channel between the posts and extending below thefloor of the body of the car.

4. The combination in a car, of a transverse beam at the end of the carbody, two corner posts spaced apart to form a channel, a structuresecured to the car body at the corner and having a channel forming acontinuation of the channel between the posts and extending to theplatform of the car.

5. The combination of a car in which the floor of the body of the car isabove the plat form, a cross beam at the end of the car, two cornerposts, a structure having two sockets, one socket receiving the outerside corner post, the other socket receiving the end of the transversebeam and the lower end of the inner corner post, said structure beingchanneled to a point about on a line with the floor of the platform.

6. The combination in a oar in which the floor of the body portion isabove the oor of the lat'form, of a transverse beam at the end of t ecar body, two corner posts, one supported a given distance from theother so as to form a channel for the reception of a door, a cornerstructure made in one piece and having sockets for the reception of thecorner posts and. the beam, said sockets being spaced apart so as toform a channel, said channel extending to the floor of the platform.

7. As a new article of manufacture, a corner structure for the corner ofa car made in a sii'lgle piece and having two vertical members, a socketin each member, said members being spaced apart to form a channel.

8. As a new article of manufacture, a corner post for cars made to formtwo members spaced a given distance apart, and a base plate uniting thetwo members, each member having a socket for the reception of a postandbraced to stiifen the structure.

9. As a new article of manufacture, a corner structure for railway carshaving two vertical members spaced a given distance apart to form achannel, one member having a socket for the reception of the outsidecorner post, the other member having a'socket for the reception of theend beam and the inside corner post, a base plate at the lower end ofthe structure, and two flanges projecting from the inner side of eachsection so as to increase the bearing surface of the section for theguidance of a door.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
